He would never leave her and does not want to let her go

Hi I'm looking for dramas where the ML does not want to let the FL go and if she did leave he would be so sad and it would destroy him. Where the ML would never leave her. There are a lot of dramas where the men are super in love but they do leave the FL for some noble reason. I'm looking for dramas where the ML would never leave her ever.

Examples  ( In A lot of these the ML does lose the Fl at one point -she leaves- and they can't stand it and don't want to let her go) (Some when they meet again hold on for dear life)

Thank you :)

In Here to heart is the ML deeply in love with her?

I watched the beginning of my love eun dong and liked it but I thought it was weird that later she was married so I gave up on it I wish she didn't marry someone else.

 Czakhareina:

She had amneseia and she was guilted over by her father and the husband to get married. They never did consunated the marrriage (i think) because he was paraplegic. But i get what you mean, i felt bad for the kid in this situation. 

With here to heart, yup he was. As spoiler, I just wanna say that he car,ried a torch for her for so long. His plans included her ,as can be seem by the way he built and designed his future home which was what she designed and dreamed off.

Thank you :) 

Oh ok that's still wierd she was married though and the main guy wanted to be with her idk how they could be together unless she divorced the guy.

Thanks so much <3 I'm going to check out here to heart then.
